USB: storage devices and SAT
Add the SANE SENSE flag to indicate that a device is capable of handling
more than 18-bytes of sense data. This functionality is required for
USB-ATA bridges implementing SAT. A future patch will actually enable this
function for several devices.
The logic behind this is that we can detect support for SANE_SENSE in a few ways:
1) ATA PASS THROUGH (12) or (16) execute successfully
2) SPC-3 or higher is in use
3) A previous CHECK CONDITION occurred with sense format 70-73 and had
a length greater than 18-bytes total
